Abstract
A window may be provided with a light modulator. The light modulator may be dynamically adjusted to control visible light transmission through the window. The window may also have layers that selectively block light with non-visible wavelengths. The light-blocking layers may block ultraviolet light, near infrared light such as light from solar radiation, and far infrared light such as heat produced due to the absorption of visible light by the light modulator. The light modulator may be a guest-host liquid crystal light modulator. The guest-host liquid crystal light modulator may have a layer of liquid crystal material with dye that is interposed between polymer substrate layers. The polymer substrate layers may be thermoplastic layers that are moldable to conform to window shapes with compound curves.
